development of products based on secretom from stem cell conditioned medium for melasma therapy

Conditions: Melasma

Summary: this research is a clinical study with a single-blind randomized clinical trial design (randomized controlled trial) in rscm-fkui this study aims to assess the effectiveness and safety of intradermal concentrated secretome injection therapy, triple combination cream, and intradermal tranexamic acid injection in melasma patients, determine the quality of life profile of melasma patients after triple combination cream therapy in melasma therapy, and determine sod levels in melasma patients. this research will be attended by 90 research subjects

melasma is a pigmentation disorder in the form of brownish macules with irregular edges caused by dysfunction of melanogenesis. melasma occurs more often in women with fitzpatrick skin types iv-vi, namely those of asian, hispanic and african descent, especially on parts of the face that are exposed to sunlight. the therapeutic modality that is being developed for melasma therapy is the secretome. the secretome is a bioactive molecule secreted by mesenchymal stem cells in a conditioned medium containing a large number of growth factors, cytokines, and various macromolecules, and extracellular vesicles including microvesicles and exosomes that can stimulate various biological reactions, especially in modulating various new tissue formations. so far there have been no clinical trial studies comparing the application methods of intradermal concentrated secretome injection, triple combination cream, and intradermal tranexamic acid injection as melasma therapy in indonesia and the quality of life profile of melasma patients tested using the melasqol-ina questionnaire is not yet known. this research is a study using a randomized controlled trial (rct) design that compares intradermal concentrated secretome injection, triple combination cream, and intradermal injection of tranexamic acid. this study was single-blind randomized to investigators. the secretome of mesenchymal stem cells from adipose tissue will be produced by ipt stem cell medical technology rscm-fkui, cmu 2 building, 5th floor, while research on subjects with melasma will be carried out at the rscm dermatology and venereology polyclinic research subjects were randomized to determine the group for intradermal concentrated secretome injection, triple combination cream, and intradermal tranexamic acid injection. subjects will be divided into 30 people per group. the research evaluation time is 12 weeks. the secretome injection group (a) and the tranexamic acid injection group (c) will be given 0.5% tretinoin cream for 2 weeks as preparation. next, all sp groups a, b, and c will undergo an initial physical examination in the form of a physical examination, clinical photos, mmasi score, melasqol-ina, dermoscopy, wood's lamp, and mexameter. group a evaluation will be carried out every 4 weeks, namely weeks 0, 4, 8, 12 with secretome injections 3 times, namely at weeks 0, 4 and 8. subjects are given facial wash, sunscreen and 0.5% tretinoin cream at night. day group b evaluation will be carried out every 4 weeks, namely weeks 0, 4, 8, 12. subjects were given facial wash, sunscreen, and refaquin cream (triple combination) for the night group c evaluation will be carried out every 2 weeks, namely weeks 0, 2, 4, 6, 8, and 12. subjects are given facial wash, sunscreen, and 0.5% tretinoin cream at night. each evaluation will be checked: * physical examination * mmasi score * ptga * mexameter examination data is recorded in research status which is then compiled into a master table. the research results are attached in the form of narratives, tables and graphs. data were processed statistically using stata v.16 (statacorptm, usa). the characteristics of the research subjects are presented in the characteristics table. characteristics with categorical data are presented in the form of frequencies and percentages. numerical data was subjected to normality analysis using the kolmogorov smirnov test and for numerical data with a normal distribution it was presented in the form of mean and standard deviation, while for non-normal distribution it was presented in the median and minimum and maximum values. comparison of mmasi scores, melanin index, erythema index, speed of decline between the three research groups, was analyzed using the unpaired t test. data that is not normally distributed uses an alternative test, namely the mann whitney test. comparison of mmasi scores, melanin index, and erythema index at each examination time with baseline were analyzed using the paired t test. data that is not normally distributed uses an alternative test, namely the wilcoxon test. comparison of the proportion of telangiectasis scores between the intervention and control groups was analyzed using the chi-square test. the pearson test is used to assess the correlation between mmasi and melasqol-ina scores if a normal data distribution is obtained, while the spearman test is used if the data distribution is not normal. the test results obtained are in the form of a correlation coefficient (r) which is in the range -1 and 1. the r value which is in the range 0.1-0.3 indicates the correlation between the two variables is weak, the range 0.4-0.6 indicates a moderate correlation , a range of 0.6-0.9 indicates a strong correlation, and 1 indicates a perfect correlation. the value of statistical significance in the research is determined
